C Correct answer
Explanation

Relative speed = 15 + 20 = 35 km/hr. Time = 42 minutes = 42/60 hours = 0.7 hours. Distance = Speed * Time = 35 * 0.7 = 24.5 km.

AI explanation

Since they are moving towards each other, their relative speed is 15 km/hr plus 20 km/hr, which equals 35 km/hr. Converting 42 minutes to hours gives 0.7 hours, and multiplying this by the relative speed gives a distance of 35 multiplied by 0.7, equaling 24.5 km. The result is 24.5 km.
